If you know your tables and number bonds,
this is quite basic!
Make sure you know exactly
what a Prime number is.
( For example: How many prime numbers
are there on the the six faces of a dice? )
48 students went on a geography field trip.
Their teachers split them into equal groups.
Suggest five different ways that the teachers might
have split up the students.
A school ran 3 evening classes:
Conversational French
Cake Making
Woodturning.
The Conversational French class had 29 students,
Cake Making had 27 students,
and the Woodturning class had 23.
For which classes did the teacher have difficulty
dividing the students into equal groups?
The tricky bit is remembering that a prime factorisation
includes all the prime
factors that multiply to make that number
so you've got to repeat some of them.
